The .zip file containing the dataset is organized as follows:

• lcvoldXXX.dat pre-impact lightcurves for all the different scenarios
• lcvnewXXX.dat corresponding post-impact lightcurves
• parameters.csv: a text-file containing \(\beta\), \(J_2\) and \(a/c\) parameters for the training scenarios (i.e. the first ones).

Columns Description

For the files describing lightcurves, the first column denotes the time (in minutes) while the second indicates the normalized total luminosity with 1 being the maximum.

Each row-index from parameters.csv corresponds to the pre- and postimpact lightcurves (e.g. row 28 corresponds to lcvold028.dat and lcvnew028.dat).

The columns in parameters.csv describe (in order) the following:

• value of the \(\beta\)-factor (>= 1)
• \(J_2\) value of the primary
• \(a/c\) axial ratio of the secondary

The goal of the competition is to reconstruct \(\beta\) and \(a/c\) for the test scenarios (i.e. those not in parameters.csv). Reconstruction of \(J_2\) is not required.
